Background/Objectives: Volunteering has been widely recognized as beneficial to the well-being of older adults, providing health benefits, increased social engagement, and a sense of purpose. This study aimed to explore the associations between volunteering and physical and mental health measures among older adults in Japan. Methods: Using an online survey conducted during the COVID-19 pandemic, 500 participants aged 65 and older were divided into volunteer and non-volunteer groups. Demographic, lifestyle, and health characteristics were comprehensively assessed using a series of reliable and validated instruments. Logistic regression analysis was used to explore the associations between volunteering and health outcomes. Results: The findings revealed that while there were no significant differences in physical health indicators and undertreatment of most diseases (with the exception of cataracts), volunteers reported significantly lower levels of depression and loneliness compared to non-volunteers. The volunteer group also showed greater engagement in social activities and hobbies, which may have contributed to their improved mental health outcomes. Conclusions: The results of this study add to the growing body of evidence suggesting that volunteering may be an effective, low-cost intervention for promoting mental health and social engagement among older adults.

Background/Objectives: In the context of an aging society, physical disability and its relationship with frailty is of growing concern. The aim of this study was to examine the associations between oral function, social participation, and loneliness among community-dwelling middle-aged and older adult physically disabled individuals. Methods: In this cross-sectional study, the participants were 140 individuals with certified physical disabilities living in the studied area. Demographic characteristics, outing activities, loneliness (Three-Item Loneliness (TIL) Scale), and frailty/ability to live independently (Kihon Checklist (KCL)) were assessed using a questionnaire survey. The participants were divided into two groups based on the presence or absence of oral dysfunction (OD), and statistical analyses were performed to compare the groups. Results: The group with OD had significantly higher TIL and KCL total scores and significantly lower mobility, confinement, cognitive function, greater levels of depression, and fewer outing activities (volunteering, movies, festivals, sports) compared to the group without OD. In a multivariate, age- and sex-adjusted binomial logistic regression analysis, outing activities (OR = 0.011, 95% CI: 0.000–0.529, p = 0.023) and loneliness (OR = 6.174, 95%CI: 1.292-29.502, p = 0.023) were identified as significant factors. Conclusions: An association was found between OD, loneliness, and social activities among middle-aged and older individuals with physical disabilities. The results suggest that future interventions should consider the relationship between oral function and factors such as depression, loneliness, social isolation, and social engagement as a means to mitigate frailty and other health and well-being concerns for physically disabled individuals.

In the current study, we investigated the motivational status and underlying factors of the motivational changes among Japanese medical science students brought by the COVID-19 pandemic. Two groups of second-year undergraduate medical science students (training to become medical technologists and/or medical science researchers) participated in this study in the summers of 2020 and 2021 by writing essays describing how the pandemic had affected their motivation to study. A content analysis of the motivation status and underlying factors (both motivating and demotivating factors) was conducted before statistical analysis was used to investigate possible differences between the sexes and the two groups. In total, 73 essays were included in the analysis. The students had increased motivation to study in both groups (89% and 62%, respectively); however, in Group 2021, 19% of the students (all women) had decreased motivation. Among the underlying reasons behind the increased motivation, students showed a desire to help/save others, contribute to the development of medical science, increase knowledge, and disseminate correct information. The demotivating factors were largely linked to online learning and the negative emotions associated with lockdown. Our findings suggest that, for Japanese medical science students, the COVID-19 pandemic has been an overall motivating experience for our students. However, the prolonged pandemic and lockdown measures could attenuate this and be particularly disruptive for women.

The purpose of this study was to examine the association between sleep quality, frailty, and human relationships in Japanese older adults (aged 65 years and above, excluding those certified as requiring long-term care). This cross-sectional study used a questionnaire survey to gather demographic information, data on frequency of conversation and conversation partners, and employed the following validated instruments: Kihon Checklist (KCL), a Japanese instrument used to determine the care needs and frailty of older adults; the Dysphagia Risk Assessment for Community-Dwelling Elderly (DRACE) scale; Japanese versions of Pittsburgh Sleep Quality Index (PSQI-J); the Geriatric Depression Scale-15 (GDS-15-J); and the University of California Los Angeles Scale (UCLA-J), an instrument to assess loneliness in older adults. The 500 respondents were divided into two groups based on sleep quality (PSQI-J): low sleep quality group (n = 167, 33.4%) and high sleep quality group (n = 333, 66.6%). Our analyses showed that the low sleep quality group had a KCL score of 5.55 ± 2.47, which indicated frailty. Binomial logistic regression analysis identified age, number of diseases under treatment, DRACE, GDS-15-J, and conversation frequency and discussion partner for important matters as factors (p < 0.05) associated with poor sleep quality. These factors could help enhance the detection of frailty and predictability of caregiving needs.

This study explores the impact of the COVID-19 pandemic on the motivation of medical students using a mixed-method, user-led approach with students as both participants and researchers. Data were collected in 2021 through essays describing students’ motivation during the pandemic. The essays were coded, categorized, quantified, and statistically analyzed for gender-based differences. Results showed that while 71% of students reported increased motivation, female students more often experienced fluctuating motivation levels. Key motivational factors included career aspirations and educational purpose, whereas demotivational factors involved disruptions to college life and mental health struggles. Notably, female students disproportionately expressed doubts about the medical profession. The study also utilized a collaborative autoethnographic method to explore the researchers’ own pandemic experiences, revealing long-term positive effects and resonating with initial findings. This research contributes to understanding the pandemic’s long-term impact on medical students and offers insights into nurturing resilient future doctors capable of handling healthcare crises.

For non-English-speaking nations such as Japan, proficiency in English has emerged as an indispensable skill, particularly in scientific fields like medicine. This research paper extends prior investigations into the motivations of Japanese medical students for learning English and delves into their willingness to communicate (WTC) in English. Importantly, it explores the impact of the COVID-19 pandemic on these motivations and communication behaviors. This study reveals that Japanese medical students are strongly instrumentally and vocationally motivated, viewing English as a practical asset for their future medical careers. They also exhibit a strong international posture, demonstrating an eagerness to engage with global cultures through English. Notably, the students’ motivation to study English remains resilient despite the pandemic’s challenges, such as the shift to remote learning and travel restrictions. However, their WTC in English exhibits nuanced changes. While overall WTC remains stable, students’ inclination to give presentations in English decreases significantly, possibly due to reduced face-to-face interactions in virtual learning environments. Additionally, their interest in participating in international events and activities wanes, possibly influenced by pandemic-related travel anxiety. These findings underscore the importance of offering specialized English classes and study abroad/international exchange experiences to sustain students’ motivation to learn English.
